4 Claims.

(Clf 19156) (Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) This application is made under the act of March 3, 1883, as amended by the act of April 30, 1928, and the invention herein described and claimed, if patented, may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment to me of any royalty there- My invention relates to new and useful improvements in cotton condensers and pertains more particularly to a condenser designed to produce a ribbon-like division length-wise of the sheet of lint cotton upon discharge from the condenser in the form of a bat of cotton.

One of the objects of my invention is to provide means for obtaining a portioned sample of lint cotton entering a cotton bale box which will be truly representative of the bulk of the lint cotton composing the completed bale.

Another object of my invention is to provide means for the collection and delivery of the sample of cotton bat obtained at a point remote from the plane of issuance at the cotton condenser of the major portion of the cotton bat.

35 The following description, considered together with the accompanying drawing will fully disclose my invention, its constructions, arrangements, and operations of parts, and further objects and advantages thereof will be apparent.

30 In the drawing:

Figure 1 is a plan view illustrating an embodiment of my invention with respect to a cotton condenser with the cover of its casing removed.

Figure 2 is an elevational section through the 35 condenser along the line 22.

Referring with more particularity to the drawing in which like numerals designate like parts, the numeral 3 designates the casing or housing of an ordinary cotton condenser connected to a lint flue transition 4, said flue serving to conduct the air-borne lint cotton from the gins. The usual screen cylinder is replaced by a drum 5 having an enlarged narrow concentric portion 6. This enlarged portion or sample area may be either in 45 the center, at one of the ends, or at any other suitable locus on the lateral surface of the drum 5. The usual compression roller 1 is correspondingly reduced in diameter above the enlarged portion 6, substantially as shown. An endless screen 5 belt 8 passes over the enlarged portion 6 and an idler pulley 9 at a suitable point in front of the condenser passing through a guide channel III and an aperture I I, substantially as shown. The channel III is disposed on the lint slide I2 and embraces the sides of the belt 8 substantially between the outlet of the condenser and the enlarged portion 6.

The end walls I3, I3 of the enlarged portion 5 are imperforate and preferably non-collective of lint cotton, such as highly polished wood and so 5 forth. These end walls extend radially and are beveled on their inner sides to provide peri heral bearings I4, I4 for the stepped ring sections I5,

I5 of the roller I. The reduced section I6 of the roller I between the members I5, I5 is preferably 1 perforated, but such perforations are not indispensable.

The operation of this invention is as follows: The air-borne lint cotton is conveyed through the lint flue transition 4 into the condenser cas- 15 ing 3 where it strikes against the imperforate end walls I3, I3, the screen surfaces of the drum 5, and the conveyer belt 8. The mass of air-borne lint cotton, striking the rotating curved, smooth, surfaces of the walls I3, I3, is diverted thereby 20 to the rotating screen surfaces of the drum 5 and to the conveyer belt 8. The said cotton is deposited on the outer screen surfaces while the air is separated therefrom and passes through said screen surfaces where it is vented from the casing 3 in the usual manner known in the art. The lint cotton is compressed into bats beneath the roller I and they are delivered through the lint slide I2 in the usual manner, except that the bat issuing from the enlarged portion 6 is carried away on top of the belt 8 through the guide channel I0 forming the sample bat, which is truly representative of the lint cotton discharged from the condenser. The sides of said guide channel l0 prevent wayward'air currents inter-felting the cotton fibers of the sample bat with the other cotton. The tangential path of movement of the belt 8 away from the drum 5 causes the disjunction of any mislaid cotton fibers overlapping the end walls I3, I3. 40

It is to be understood that this invention may be modified by making the sample area 6 smaller than the main body of the drum 5 instead of larger, with corresponding changes in the roller I, such a modification being a mere reversal of parts within the scope of anyone skilled in the art. Also other types of cotton condensers may be employed, the type shown in the drawing being chosen for the purpose of illustration because it is one of the simplest known in the art.

Having thus described my invention, I claim:

1. In a cotton lint condenser, a condenser cylinder having a small portion of its lateral surface enlarged concentrically, a compression roller coacting with said cylinder, having a portion thereof recessed complementary to said enlarged portion of said condenser cylinder, a perforated conveyer belt disposed about said enlarged portion and about an idler pulley in front of the condenser, and a guide channel projecting from said enlargedsection to the exterior of the condenser and embracing said belt.

2. The apparatus as defined by claim 1 in which the recessed portion of the compression roller is perforated.

3. In a cotton condenser, a cylinder'having a screen lateral surface and an off-set concentric portion, said off-set portion having a screen lateral surface and radially extending beveled imperforate end walls, a compression roller co-acting with said cylinder, said roller having a concentric oiT-set portion complementary to the offset portion of said cylinder and co-acting therewith, ascreen conveyer belt operating on the surface of the off set portiomotsaid cylinder beneath the off-set portion of said rollenand guide means embracing the sides of said conveyer belt substantially between the outlet of the condenser and 5 the ofl-set portion of said cylinder.

4. In a cotton lint condenser, a condenser cylinder having a small portion of its lateral surface concentrically reduced, a compression roller coacting with said cylinder having a portion therell} denser, and a guide channel embracing said belt 15 and projecting from said reduced portion to theexterior of the condenser.
